Oscillatory and non-oscillatory solutions of dynamic equations with bounded coefficients
Electronic Journal of Differential Equations, 2018 We analyze second-order half-linear dynamic equations on time scales. We prove oscillation and non-oscillation criteria which are sharp in the sense that the considered equations remain uncovered only for one setting of their coefficients.

A Force Method Model for Dynamic Analysis of Flat-Sag Cable Structures
Shock and Vibration, 2009 A new force method is proposed for analysing the dynamic behaviour of oscillating cables with small sags. The accepted dynamic model of such cables reduces to a partial differential equation (the equation of motion) and an integral equation (the ...

Coagulation Equations for Aerosol Dynamics [PDF]
, 2021 Binary coagulation is an important process in aerosol dynamics by which two particles merge to form a larger one. The distribution of particle sizes over time may be described by the so-called Smoluchowski's coagulation equation. This integrodifferential equation exhibits complex non-local behaviour that strongly depends on the coagulation rate ...

Sparse learning of stochastic dynamical equations [PDF]
The Journal of Chemical Physics, 2018 With the rapid increase of available data for complex systems, there is great interest in the extraction of physically relevant information from massive datasets. Recently, a framework called Sparse Identification of Nonlinear Dynamics (SINDy) has been introduced to identify the governing equations of dynamical systems from simulation data.

Dynamic spectrum access mechanism based on graphical evolutionary game in radio networks
Tongxin xuebao, 2015 In order to realize efficient data transmission for users in radio networks,a dynamic spectrum access mechanism based on graphical evolutionary game was proposed for the bounded rationality characteristic of users,while graphical game can better reflect ...

Wilson–Cowan Equations for Neocortical Dynamics [PDF]
The Journal of Mathematical Neuroscience, 2016 In 1972-1973 Wilson and Cowan introduced a mathematical model of the population dynamics of synaptically coupled excitatory and inhibitory neurons in the neocortex. The model dealt only with the mean numbers of activated and quiescent excitatory and inhibitory neurons, and said nothing about fluctuations and correlations of such activity.
